Answer:
Friction
Explanation:
Friction keeps things from sliding into things according to newton's laws
We have that the speed of the ice at the bottom is mathematically given as
v=1.8812m/s
<h3>The speed of the ice at the bottom </h3>
Question Parameters:
A 8.00 kg block of ice, released from rest
at the top of a 1.50-m-long frictionless ramp,
slides downhill, reaching a speed of 2.70 m/s
constant friction force of 10.0 N parallel to the surface of the ramp
Generally the equation for the Potential Energy is is mathematically given as
P.E=K.E+W_{fric}
Therefore
mgh=0.5mv^2+W_{fric}
Where
W_{fric}=F.S
W_{fric}=10*1.50
W_{fric}=15
And
mgh=0.5mv^2+
h=0.3719
Hence
0.5(8.00)(v^2)=(8.00)(9.8)(0.3719)-15
v^2=3.53924
v=1.8812m/s
